void setStatus (in boolean aStatus) - Sets the status
of the sensor to on (true) or off (false).

??? getValue () - Returns the value of the sensor.
The return type depends on the sensor. For example, a pressure
sensor returns one value, while a camera would return an array or
string. The value should be something reasonable for the sensor
and consistent with the sensor specification. The value returned
when the sensor is off should be different from the on value.

Implement the server code to accompany your IDL above, and implement a
client to exercise your server. Your server should not block waiting
for CORBA calls - it should run continuously.
